AI Appraisal Estimate

This is a luxury sports wristwatch featuring the iconic octagonal bezel design associated with the Royal Oak line. The timepiece is constructed from stainless steel with a vertically brushed finish on the flat surfaces and polished chamfers on the lug edges. The bezel is secured by eight functional hexagonal screws. The dial displays a black 'Méga Tapisserie' pattern with applied white gold hour markers and hands, both filled with luminescent coating for visibility in low light. A distinctive feature is the internal rotating diving scale located on the flange, which is operated by the crown at the 10 o'clock position. The primary winding and adjustment crown is located at 3 o'clock, protected by substantial guards. Both crowns appear to be finished in black rubber or ceramic. The watch is mounted on a black integrated rubber strap designed specifically for the Offshore case geometry. Visible condition indicates moderate wear, including minor scuffing on the steel bezel and case edges, particularly around the 5 and 7 o'clock mark. The crystals appear clear with no significant chips or scratches. The branding 'Audemars Piguet' is printed clearly below the 12 o'clock double-index markers. This model represents a contemporary iteration of the 15703ST or 15710ST references, characteristic of 21st-century high-end horology.

I have examined the provided description and visual characteristics of this Audemars Piguet Royal Oak Offshore Diver, likely reference 15703ST or the subsequent 15710ST. My assessment identifies the signature mega-tapisserie dial, the internal dive bezel controlled by the 10 o'clock crown, and the brushed stainless steel construction. The presence of moderate wear—specifically the scuffing noted at the 5 and 7 o'clock positions on the bezel—is consistent with a pre-owned luxury sports watch and slightly moderates the valuation, as the bezel's vertical brushing is notoriously difficult to refinish without losing sharp edges. The market for the Offshore Diver remains stable; while prices have softened from 2022 peaks, it remains a cornerstone of the 'haute horlogerie' sports category. Current secondary market data shows comparable examples with visible wear trading in the $18k to $22k range depending on the presence of the original box and papers. Limitations: This appraisal is based solely on visual descriptors and image analysis. Definitive authentication is impossible without a physical inspection. A professional horologist would need to examine the movement (Calibre 3120) for finishing quality and beat rate, check the 'feel' of the screw-down crowns, and verify the serial numbers against AP's archives. To reach the high end of the valuation, provenance documentation and service records would be required to ensure the water resistance seals remain intact and the movement is within COSC specifications.
